HPE Zerto Software Reviews

We do a semiannual disaster recovery test, usually one in January and another in September, where we fail our entire company over to our Arizona DR facility. We run the business out of the Arizona location for the day. In order to be able to do that, the Zerto application allows us to migrate 58 machines over to that location and allows us to run our business from that location for the course of the day.

We are able to have a successful disaster recovery solution through using Zerto for our Disaster Recovery drills. We are able to fail over anytime, day or night, to run our applications out of our Arizona facility. Within a 15 or 20 minute time frame, we can have those application servers up and running in Arizona. It is just a huge help to have a successful, reliable disaster recovery solution that we know at any point in time, within 15 or 20 minutes, can be running out of a different location.

Most of the time, this is at least a two person job. Previously, when we had a disaster recovery drill it would take two of us working for three or four hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I'm able to finish my work in about 30 mins and be available onsite to help and assist anybody else as needed during the disaster recovery drill. Its ease of use and the ability to have a reliable solution for disaster recovery has become invaluable to us.

There is built-in active logging if needed for a longer retention period. If we fail a machine over and are just doing tests for it, we can fail it right back at the end of the failover without much issue. We couldn't do that with SRM. The ability to keep track within the activity log of what is going on with the VM, then fail it back prior to the one-hour time frame that we have set up without having to worry about it losing data during our tests or production failover drills.

The product is very easy to use. On a scale of one to 10, I'd say it's a nine as far as ease of use goes. In order to do an update in our old product (SRM), we basically had to take down almost our entire vCenter to be able to do the updates. Whereas, I can do updates to our Zerto product within 30 minutes to both our ZVMs in Massachusetts and Arizona. We haven't had problems troubleshooting after doing upgrades. Within five minutes, we can configure a whole new cluster solution and work on getting it synced out to Arizona.

It transfers up-to-the-minute files. Therefore, if something was to happen and the business was to go down Massachusetts due to a server failure, we could simply fire up those VMs in Arizona within approximately five minutes. The data protection level is top-notch. We haven't lost any machines, data, or VMs during the course of utilizing this product.

The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't give you accurate information on the error message to be able to tell us what's going on without having to go actually login into Zerto to determine what's causing the issue.

Another issue with the alerting is that it will pause a job. E.g., if we have something running from Massachusetts to Arizona, but a VM has been removed, updated or moved to a new location in vCenter. It literally pauses the VPG the VM resides in but will never give us a notification that it's been paused. Therefore, if we had an issue during the course of the day such as a power event and we needed to gain access to those VMs in some sort of catastrophe, we wouldn't be able to get access to them because that job was paused and were never notified about it being paused for whatever reason. It would therefore be a big problem if the VM was needed to be recovered and we didn't have those resources available.

It would be great to get more precise alerting to be able to allow us to troubleshoot a bit better. Or have the application at least give us a heads up, "A VPG job has been paused." Right now, it's sort of a manual process that we have to monitor ourselves, which is not a great way to do things if you have a superior disaster recovery solution.

Almost two years.

The stability is rock-solid. Nothing has gone down since we installed it; there has been no downtime.

Typically, once a quarter, we have an update. Last year we were at version 7.5, then we recently went updates to 8.0. On top of that, they release security patches and other things to improve bugs they find in the program. Right now, there is a U4 version that's out, which we will be updating to this quarter.

In the U4 version, there are security enhancements because a lot of zero-day issues that are being found in a lot of the applications. Zerto is making more security modifications and enhancements to the encryption between one location and another, so somebody can't hack your data and access it while it's in transition.

Scalability is very easy. We are going through a POC right now because we want to branch out to the cloud. Just getting that set up and going through the process was about 60 minutes.

It's very scalable and extendable. We can do one to many solutions, as far as where our disaster recovery is going. This is what we wanted. We would never have been able to do that with our SRM product.

There are two engineers trained to use the product. I'm the primary contact for the application and do most of the work on the product. One of the storage guys handles a lot of the storage set up on the back-end with me. We have at least two people trained on each application that we have in-house. Both of us are in charge of making sure the application is up-to-date and doing what it's supposed to be doing. 

Zerto's technical support is very good. They are very reliable and always very pleasant to deal with. We've never an issue working with them. They usually come back with the precise solution to whatever we are troubleshooting.

Our issues are usually user self-inflicted. E.g., we remove a host out of the cluster to upgrade it or do something else with it and don't follow the correct procedure that's needed in order to be able to shut down the Zerto appliance correctly. If somebody doesn't follow that procedure, because they either don't know how, weren't aware of it, or just skip that step, then it causes problems inside of Zerto. This will pause jobs and the VPG will no longer be accessible on that host. Sometimes it's easy to get it back up and running again. Usually, when you put a new piece of hardware in the cluster that has a different set of parameters with its hardware, then the appliance will be missing because it was taken out with the old hardware. Usually, you need to get their technical support involved in order to be able to troubleshoot the issue with them to be able to get the VPG back online again on the new hardware. As I said its self-inflicted most of the time because steps are missed with our processes.

The documentation that we got from them was in depth and work well when needed, if you follow them correctly you will have success. If you don't follow the steps, that's when problems develop. Therefore, it's not a fault in their documentation, it's a fault of the user who's not following the proper steps for success. It doesn't happen often but I think we have contacted technical support only three times in the two years that we've had the product.

For eight years prior to using Zerto we used to use a product called SRM, which is part of VMware. We finally switched over to Zerto after having them come in and do a presentation for us. This was after trying for about a year to do that and convince our vice president to allow us to migrate over to a different platform.

The reason why we used SRM was because SRM was built into our VMware vCenter licensing. We never had a successful DR test during the previous couple of years with SRM. By switching over to the Zerto product a year and a half ago, we were able to run a successful disaster recovery test within three months of switching over. We had our first successful disaster recovery tests in two and a half years because Zerto made our life so much easier and helped getting servers over to a new location almost seamlessly. 

In order to be able to have a successful disaster recovery, we need to be able to successfully migrate 58 servers from our Massachusetts location to Arizona. On previous attempts, we got about half the stuff over there, then we'd fail. In other scenarios we would get everything over there but some of the machines wouldn't come up because of the way they were configured. One time, the business was down for about half the morning because it took us that long to get the stuff back up and running using SRM. This was a real pain point for us, getting this product in place and working successfully. It took Zerto to be able to finally get us to do that. It's been a lifesaver. All we had with SRM was nothing but headaches.

The initial setup was very straightforward. We had everything running in half an hour. It got deployed with two virtual machines (ZVMs): One got deployed in Massachusetts and another in our Arizona location. From there, we deploy appliances to each one of the hosts that's inside of the clusters that we are managing for our disaster recovery solution.

Within 30 minutes, we had it deployed to our entire production cluster and the hosts in here. After that, we just started creating jobs, which took quite awhile to do because we have a lot of large servers. However, that's not the worry of the Zerto application, but the size of the VMs we have in production. 

For our implementation strategy, we just mimicked what we had in place for our SRM environment. Our 58 machines are spread across different clusters: some in our DMZ, some in our prod and some in our WebSphere clusters. After that, we ran two tests to ensure that we were able to fail over to our Arizona location then fail back without any changes or modifications to the VMs. Once we did that, we started rolling out to each of the clusters, one Virtual Protection Group (VPG) at a time. I think we now have 23 VPGs total.

We worked with an outside vendor (Daymark) who does a lot of our work through outside vendors. They work with Zerto directly. When we set it up originally, we had a Zerto technician on the call as well as a Daymark technician on-site working with us.

Our experience with Daymark has been very good. We love working with them and try to use them for our integration and infrastructure work. They are a very good company that are easy to deal with. We try to use them as much as we can. Thanks to Rick and Matt for a great working relationship.

We have seen huge ROI.

It used to be a three-person job, and now it only takes one person to manage and run the process. The fall back is the same thing. We've never had any issues with stuff coming back out of Arizona to our Massachusetts location. Within 15 to 20 minutes, we can have our servers successfully migrated back, then up and running just as they were originally without having too many conflicts or configuration issues. 

The solution has helped us reduce downtime in any situation that we have come across, thus far, for disaster recovery at a 4:1 ratio.

We are an insurance company therefore, if we're down for an hour, it's thousands of dollars being lost. E.g., people can't pay their insurance bills, open new policies or get the support they need for an accident.

These things have been invaluable to us:

• Not having to have so many bodies onsite during a disaster recovery drill.
• Not having to worry about multiple people dealing with the application.
• The product's reliability of always being up and running and not having any issues with it.
  

It's very equitable, otherwise we wouldn't do it. It's something that we utilize for the licenses per host used. Therefore, it's very cost-efficient as far as the licensing goes. For the amount of stuff that we have configured and what we're utilizing it for, the licensing is not very expensive at all.

There is a one-time cost for maintenance and support. We have a three-year contract that we will have to renew when those three years come up. There is also licensing on top of that for whatever product you are using it depending on the host configurations.

Right now, we use Veritas. We will be evaluating Veeam and Rubrik as a new solution for our backups in the next quarter or so, on top of the fact that we may decide to use Zerto. The three of them are in the mix right now for when we decide to switch over vendors for a better backup solution. 

Zerto gives you the ability to utilize it as a backup solution, but it's not a true backup solution because it can't do file level backups. If you want a particular file off of a server, it can't do that for you. What it can do is give you the whole server, then you need to go back and pull that file off it. Mainly for that reason, we haven't chosen to use Zerto and may never use Zerto as our backup solution. The other solutions allow us to get a file level backup.

Don't hesitate. Go out and do it now. Don't wait two years like we did. Push harder in order to be able to get the solution in place, especially since we know it will work better for you. Don't just take, "No," for an answer from senior management.

The application is phenomenal. They continually add new things, more plugins, and modifications to the way things work. It just gets better as they go.

We don't plan to use the solution for long-term retention at this time, but we are looking at going into a hybrid cloud solution in the near future which we may be using long-term retention for to make a duplicate copy of everything we have in our Massachusetts data center into a cloud solution. Whether it be an Azure or Amazon location on the cloud.

While I can't really speak to whether it would allow us to do it, the application is set up to create a duplicate of the actual servers in Arizona. That's how it works so quickly. If we ever had a problem, I could always revert back from the duplicates that we have out in Arizona using the application, if necessary. Luckily, we haven't had a need for that, and hopefully never do.

I would rate this solution as a nine (out of 10).

Our main use case for this solution is disaster recovery, migration and app testing.

Zerto helped to reduce downtime. I worked a lot in a consulting capacity and experienced DR situations where XYZ was down or a data center was down. Using Zerto to get them back up and online was a lifesaver.

Zerto reduced the staff involved in data recovery. It's a tool that allows you to do a lot just with one person at the console.

The most valuable feature of this solution is the live migration. 

This solution could be improved by being more cloud agnostic. 

I have been using this solution for eight years.

This is a very stable product. I've never heard anybody complain about its stability. I would say it's probably one of the best out there.

This is a scalable solution. 

The technical support for this solution is good and their staff are knowledgeable and able to assist quickly with resolutions. 

I would rate them a nine out of ten. 

Positive

I've used several other products including Site Recovery Manager. Zerto is the easiest to learn. There is much less of a learning curve. Other tools specific to VMware are now trying to emulate what Zerto has done to make processes easier. Zerto was a huge step in making things more simple to manage. The app works really well and integrates with VMware really well. 

The initial setup is straightforward, especially if those setting it up understand the company's infrastructure. The problems are not directly related to Zerto itself. They're always related to how the infrastructure is set up or how the network itself is segmented and having certain people that have control or access and others that don't.

The return on investment is in the ease and functionality of the tool as opposed to actually a gain from using the tool.

There may be less expensive solutions on the market but with Zerto, you get what you pay for. A lot of people don't like to think about the price until it's already happened and then the price is too high because they would be losing either way. It's better to think about it and pay for it upfront than pay for it after the problem.

We previously used and considered Site Recovery Manager.

I would rate this solution a nine out of ten. 

We use it mostly for VMs that are hosting client-facing applications and mostly client databases. We replicate 100 servers; we have 100 protected VMs.

We've never had any major headaches with the virtual-protection groups. They seem to work exactly as they should. If there's ever an issue with replication, we know right away, so it's all been very reliable.

Zerto is much easier to use than Veeam when you compare the two in terms of ease of use. Everything is very straightforward and simple in the Web Client. It's very clear if something is wrong, and everything in the Web Client works great. In Veeam, it's a little more complex; I find myself having to look through long error messages when a job fails. Whereas with Zerto, if I see a red VPG I can click on it. I would then know exactly which VM is having an issue, and I can try to troubleshoot the issue.

The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released.

We were facing a vulnerability, so we had to choose between patching our vCenter to address that vulnerability, which would break the Zerto operability, or leaving it as is with a potential vulnerability. That was really the main issue we ever faced with Zerto.

I've been working with Zerto for the past three or so years, but my company used it before I started working there.

Zerto is very stable. I've never had an issue related to stability with Zerto, and anytime we have had any potential issues, we get alerts from Zerto. It has always been a simple fix. Also, the issue has never had to do with the platform; it's always been a VM that was powered off or deleted.

Technical support has been pretty sufficient. I've only had one or two cases ever that weren't related to looking for a release date, but I've had pretty good success with them so far.

I would give technical support a rating of eight out of ten. They've never particularly impressed me, but they've always done their job.

Positive

I was not present for the initial setup, but I deployed Zerto Virtual Manager. It was pretty straightforward. You walk through the wizard, and if you have all your networks on the server and everything is done correctly, you can start to build VPGs right away.

If you have all of the network and firewall rules already in place, you could probably stand up a new one in 45 minutes.

It's a pretty set-it-and-forget-it type of tool, and it's very reliable. So, I would rate it an eight on a scale from one to ten.

We use it for DR and general backup. We have snapshots or shadow copies with Microsoft and we do Zerto backups to our other locations so we can always get the data back.

We bought Zerto, in the beginning, to migrate a very important system of the airline from a co-lo that was managed by the co-lo to our on-prem. As an airline, you can't be down because you could cause a ground stop. With Zerto, we were able to migrate all those things across to on-prem without touching anything or losing any time. We took very little downtime.

Also, we've run into some situations where, for some reason, Windows has lost some of the files. I have been able to fail it over to our other data center and they were back up in 10 minutes.

The speed of recovery with Zerto versus other disaster recovery solutions is vastly better. Whereas with the others, I'd have to spin through a lot of stuff and find things, with Zerto I can scroll back in the GUI, find the one I want, and restore it. If that's not right, I can destroy it and go back a little bit more in time.

And our being an ultra-low-cost airline, we don't have staff, so it helps in that way.

It has also helped our DR testing because we can fail over the main part that runs the airline within 45 minutes. The first time, it took me an hour and a half. The second time, it took about an hour. The last time I did it, it took about 45 minutes. That's within the timeframe of one hour where we don't have to do a ground stop.

Moving the VPGs from one location to another is a valuable feature. You just click on it and move it and it's done. We have a stretch VLAN between our data centers so it's really easy: this is IP here and the same IP is there. So if something happens or somebody wants to test something, I can fail it over.

Another aspect that I use a lot is that I can fail it over into its own little bubble and I can install software that I want to test to make sure it doesn't break something. I can do that and then roll it all back.

If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens. 

The other thing that I've run into lately is that when I've done a whole bunch of upgrades to systems, so they're offline, they get stuck in a pending state. You can never get them out so you have to delete and start all over again. It would be nice if they could make it a little simpler to figure out what's wrong.

I have been using Zerto for about six years.

It always just runs. I don't have to worry about it or keep checking it. It just does its thing.

It's very scalable. Fortunately, we bought a bunch of licenses when we first bought it and we've been growing into those licenses over the years. It has been very scalable for us.

The technical support has been good, although I've had a couple of situations where they've said some things that were totally inaccurate. But you have that in all organizations.

Positive

Since I started with this airline, we have gone through two other solutions. Zerto is the third and we've stuck with it for quite a few years.

One of the other solutions was a direct product that dumped everything to a storage area in the cloud and it never was consistent. The other was a Dell application backup that no longer exists. That was just too limiting and its backup was never consistent.

Zerto is much easier to use. Once you get the concept down of what it's doing, it's really easy to bring up backups, restore backups, move things around, and test things. It's very easy.

I had one of their sales reps in Colorado help me through the setup. Then we just took it over.

The ROI is in "funny money." It's my time and how long something is down or how long it takes somebody to restore something, and that is much faster.

The pricing seems really good. We're an enterprise customer, so we get all the bells and whistles.

We evaluated a couple of things, but one of our co-los was actually using Zerto so we looked at it as a result. That is what led us to buy it.

We use it for disaster recovery, by replicating to our DR data center.

It has simplified our disaster recovery plan. With VMware SRM it was a little bit more complex. Zerto adds more granularity, but not at the expense of complexity.

The most important features are the 

• simplicity of recovery 
• wider capabilities and feature sets than SRM has.

I have been using Zerto for about three years.

We've been using it since version 7. Since then, it's gotten better and better. We've had some bad experiences with DR tests where everything went sideways and we had to restore a bunch of VPGs or recreate them. It seems like those situations are happening less and less as the product develops.

We have 1,200 seats and we have about 1,000 VMs that are replicated. So far, scalability hasn't really been an issue. We haven't run into a problem scaling it out.

I haven't been a super big fan of the support area. The support could really be better in terms of responsiveness. I've had some issues that took two or three days to get resolved. Once I got to the right person, they were resolved quickly, but it took a while to get to that person.

On a scale of one to 10, today I would rate their support at about a seven. If you had asked me two years ago, I would have rated it at three.

Neutral

We were an SRM customer and moved to Zerto. We had issues with SRM and I think we had some issues with Zerto initially. We've had it for three years and we've gone through several revisions. With every revision, it seems to get better. They keep adding feature sets.

SRM and Zerto are really the primary competitors. We like the fact that Zerto does VM-based replication instead of having to involve storage-based replication. You can just point to an instance of it and say, "Replicate to this DR data center," whereas SRM is a little bit more complex in that context.

The speed of recovery between Zerto and SRM is similar. With the later versions of Zerto, the recovery speed has become a little bit faster.

It's very straightforward to set up. You just install the software and point it at your vCenter. There are not really a lot of overly complex parts to the installation. It installs relatively easily and quickly.

We did it ourselves.

We haven't seen ROI because we've not ever had to recover anything. But in an instance where we would have to recover from a disaster, we would definitely see ROI. It's like paying for insurance. You don't really see any value in it until you need it.

The licensing is a little bit steep, but there is some value that you do get for it as well.

In our usage, Zerto has not helped to reduce downtime or the number of staff involved in a data recovery situation. It also hasn't reduced our DR testing. We do a DR test regularly and that is about the same as it was.

I don't have any advice, but I would absolutely recommend it. The simplicity of how they have laid out the VPG structure, and being able to separate those out into groups, as opposed to SRM where you're replicating everything, seems like it's really well designed.

We use it to protect VMs. Disaster recovery is our use case. Our compliance requires that we need to simulate a DR exercise every six months if we are protecting a VM. One of the features of Zerto is simulating a disaster recovery exercise in case of failure. We fail back the VM to the DR site, and when the event is over, we fail it back to the production site.

We are using one of the newer releases, but we are still six months behind.

It meets our SLAs for RPOs and RTOs.

• Replication
• Failover and failback for DR

It needs more documentation and automation features. I would like more documentation on designing an environment and network operations. On the automation side, I would like automation to clean up the environment in cases of a failed DR effort. An API interface to perform the DR exercise would also be nice.

I have been using Zerto for seven years.

It is stable. We have had no big problems. 

There have been a few minor upgrades.

It is scalable. From a few hundred to 5,000, it has been pretty easy to scale, not only horizontally, but also vertically.

Zerto is protecting a couple thousand VMs.

The support is very good with quick response times. They are helpful. If you open a session, they will take over and immediately solve your problem. I would rate them as nine out of 10.

Positive

We have used SRM and Veeam. 

Zerto is a better product. It has more modern features. It is easy to use. It also has a good interface with command line for scripts.

The initial setup was very straightforward. The solution is easy to implement. You implement it and it starts working out-of-the-box. There is not much configuration required. It takes a couple of hours to have it up and running, protecting you.

We deployed the system ourselves.

We have seen ROI with the RTOs, RPOs, and speed of recovery.

Using Zerto, you can have your VM up and running in a matter of minutes. All you need to do is flip a switch, then you are good to go.

For speed of recovery, Zerto is faster than SRM. SRM takes more time and needs some manual effort. Veeam is pretty good and on par with Zerto.

Do a PoC. You can compare it with other products, like SRM and Veeam. Then, you will see that difference. It is good to have the solution working in a lab. Or, engage Zerto who can assist you in building a lab for it.

I would rate the solution as nine out of 10.

We use it for a hot DR site for our primary production environment, allowing us to fail over all of our production servers in case of an emergency.

We are in a much better position as far as our data protection scheme is concerned, with Zerto. Compared to where we were before, it's a night and day difference, because we didn't have the ability to immediately fail over our production environment. The difference is pretty extreme for our organization. We went from just having SAN snapshots to Veeam backups, and now we have replication.

It massively decreases the time needed for us to fail back because, before, we had no way to do so for our workload. It would have been a manual process to move our workload somewhere else. We would have had to get the VMs off of the existing infrastructure and we would have had to create a whole new infrastructure and get them running somewhere else. That could take two to three weeks, in an emergency situation, with our entire team working on it, versus just pushing a button and moving it right now. We're in a whole different realm now.

There would also be massive savings in manpower to do that. We would have to create a whole new infrastructure, whether in AWS, Azure, or even procuring physical equipment and deploying it. Now that we have Zerto in place, it's there waiting and being replicated too.

The fact that it just works is important to us. We don't have to do a whole lot to it. It does its thing in the background and it's ready to go. It enables us to execute our DR plan at any time that is required. It doesn't seem to require a lot of time or management or day-to-day maintenance. 

It doesn't "complain" a lot and it's ready to go at any time, so you could call it easy to use. It's just me responsible for maintaining it, and there is a network infrastructure person involved as well. But it mostly maintains itself, once it has been deployed.

It does what it's purported to do, which is to provide continuous data protection. We have a five-second RPO. It's definitely doing its job. It's there in the background, replicating constantly.

I would like to see them continuously improve Zerto's automated functions, such as putting hosts in maintenance mode within vSphere and not having to worry as much about how Zerto is going to react. Rather, Zerto should be able to handle putting various hosts, within either the source or destination side, into maintenance mode without having to worry about the vRA appliances. Sometimes, Zerto almost holds the vSphere environment hostage when it comes to taking certain actions. You really need to be cognizant about what you're about to do. They should further automate that and increase Zerto's ability to handle things like that in a very slick, automated way, without intervention.

Zerto could also build more canned automation tools within their product, tools that automatically work with DNS updates to AWS or Azure. Maybe they could provide an area for scripting help or canned scripts, a community or a place where people could grab some scripting. Maybe they could reach into Citrix or F5 load balancer APIs.

Also, if you have a host go wrong or you need to put one in maintenance in an emergency situation, especially on the source side, it can require you to fix Zerto and redeploy vRAs or redeploy the little appliances to the host that they're going to be on.

Also, depending on what resources it has available, storage or vSphere-wise, I'd like to see it able to balance itself out within the virtual environment, with its storage usage on the destination side.

I've only run into these things briefly, so I can't speak about them at the deepest technical level, but I have noticed that they're not as perfect as they could be.

I have been using Zerto for three months at my current company, but I have about two years' experience with it in total.

For the most part, it has been stable. There have been a few points where I have had to delete the VPG group, re-replicate data, and start over, to get things back to a good spot. But overall it has been pretty stable.

We are only protecting 45 VMs. We're not a large, multinational, so I can't really speak about its scalability.

I haven't used the technical support very much.

We didn't have a previous solution, other than SAN snapshots. That's why we looked to put something in place. Previously, we were in a tenuous situation that would make anyone nervous. We went in this direction so that we wouldn't have to be nervous.

It didn't seem that difficult to set up. 

It took a couple of days, but that didn't include setting up the SAN and the secondary sites and all of the infrastructure around having it work directly. But just the Zerto solution itself did not take very long at all to set up.

Everything that we needed to do to facilitate the use of the solution was more involved and took a month or so. At the time, we also deployed a Veeam solution to do the long-term storage, and that was wrapped up in the same project, so it's hard to give an exact amount of time for the deployment. 

Everyone knows Zerto is a little on the expensive side, but what else is there on the market that does the same thing? It is more expensive per client, for what it does, compared to a backup product like Veeam.

We didn't really go into a full evaluation of other solutions. We took the recommendation of our VAR. They're a company that provides us with help in implementing projects. They recommended going to Zerto, and I had already used Zerto before at another company, so I was comfortable with that recommendation.

Zerto serves a very specific purpose in our environment, which is to fail over the entire environment in an emergency, very quickly. Veeam claims to be able to do that, but I don't think it does it as quickly or efficiently as Zerto.

The main thing is to make sure your network infrastructure is designed properly. Zerto is only going to be as successful as the network infrastructure and the automation that is created around it to help with a failover situation.

In our particular situation, we have a stretch network situation, which means we don't really have to do a lot of the automated scripting that most people might have to do, surrounding re-IP-ing the environment and DNS updates. We're in a unique situation. Because we are a telco, we own our entire network and we have the ability to stretch our network to a location that's a state away. That scenario doesn't apply to a lot of other business situations. Other institutions may not have that luxury, in which case their scripted automation, and how well that is set up, would be critical.

Because we weren't doing backup and DR management before, Zerto has probably increased the amount of staff we need. You don't need staff in place for things that you aren't doing.

HPE bought Nimble and made Nimble not as good. Hopefully, the HPE acquisition won't have a negative effect on Zerto. That's a deep concern among all people who have had to deal with things that HPE bought. They need to keep to the original intention and vision without diluting it within some other HPE product or some other HPE offering. I have no interest in seeing Zerto losing its functionality or having it rebranded as some other problematic HPE solution. We bought this as a purpose-built solution to do exactly what we want and that's the way we would like it to stay.

We didn't have any kind of disaster recovery solution in our environment, whatsoever. We're using it for disaster recovery.

The biggest benefit we get from using Zerto is due to the fact that we have to answer to our gaming authority and prove that we have a DR solution in place. With Zerto we can do it out-of-the-box: do a test restore and actually have documentation that we can provide to our auditors.

Also, before Zerto, we didn't even have a way to fail back or move workloads. Now we do, and we can do so with a few clicks.

When it comes to continuous data protection it does the job. With the RTOs and RPOs, it does exactly that. It's the only one that I've seen that you could call a continuous data protection solution.

And one of the most valuable features, something that I wasn't even anticipating, is the file backups. We weren't even considering Zerto to do restores, but it actually is able to do that. Eventually, we could just use this as our backup solution.

It's easy to use. Once I got it installed and going, it was less than a day until I was already confident about using it. I've done numerous upgrades since then without any third-party support.

The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates.

I have been using Zerto for going on two years now.

It's rock-solid. I haven't had any issues whatsoever.

From what I've seen, because I have four different vCenters coming into it, I'll be able to scale out as much as I can physically handle on the storage side.

We're currently protecting about 100 terabytes with Zerto and we plan to increase our usage of it.

We're not using Zerto for long-term retention right now, but we do have plans to do so once we get some hardware that we can use for that.

Their tech support gets to the point. They've really been on-task and I haven't had to wait for anything. They've provided me with what I was after or answered any questions that I had.

Positive

I did the initial installation, and it was very straightforward. I've never had a solution that is this intensive and yet this easy to deploy. It took a few hours to deploy.

And in terms of working with Zerto on a day-to-day basis, it's just me.

We haven't calculated an ROI, but just comparing what it's been able to do for us, versus not having a solution, there has been ROI. It has the potential to help reduce downtime. Fortunately, we haven't had any, but it puts something in place to help us if we were to encounter some downtime. We're a casino, so every hour that we're down we lose hundreds of thousands of dollars.

Obviously, I wish it were cheaper and more affordable. But I get what I pay for, so I can't complain.

I looked into the VMware solution, but it was just way too complex. It seemed like it would require a longer deployment and fine-tuning well beyond what it took me to deploy Zerto.

The fact that Zerto provides both backup and DR in one platform wasn't very important at the time. I've seen the benefit now and I'm happy that it does, but it really wasn't a factor in what I was looking for.

The only lesson I would pass on is that when we updated VMware, that version of VMware wasn't supported with the version of Zerto we were running. That could be a "gotcha," so make sure the hypervisor is supported under the Zerto matrix.

Request a trial. It's simple enough to install and configure on your own. My advice would be to see, firsthand, how easy it is.
